`IMPROVEMENT IN RECIPROCATING CHURNS.

Specicationforming part of Letters Patent No. 139,658, dated June 10,1873; application filed March 8, 1873.

l ment attached to a cl1urn-body,with a portion of the wall broken out. Fig. 2 is a perspective of the attachment detached. Fig. 3 is a perspective of the' dasher and rod.

It is an undisputed fact that the fatty matter .from which butter is made is secreted in small sacks or globules. lIt is the office of the churn, by agitation, to break up these globules and release such fatty matter, which is then gathered and termed butter.

The nature of this invention is to construct a churn that will more quickly release the fatty matter from the sacks than is done by those in ordinary use, thereby greatly facilitating and reducing the labor of churning. The invention consists in an adjustable perforated 'cylinder inside the churn-body, as more fully hereinafter described.

In the accompanying drawings, A represents an ordinary cylindrical churn-body, and B a smaller cylinder, provided with a foot-flan ge, a, upon which the cylinder B rests; also, it is provided with a cap, which is secured upon said cylinder B by an ordinary stove-pipe joint, the cylindrical part d ot' the cap being elongated, to allow the extension or shortening up of said cylinder B, to coincide with varying lengths of churn-bodies. This cap `is this cylinder B may be rigidly secured to the l center of the bottom of `said churn-body, and the cap may be in like manner secured to the under side ot' the cover, so that when the cover is tted onto the body the cap will at the same time iit onto the inner cylinder. This, however, is not necessary, as the lianges a h will hold it in place, the former resting on the bottom of the churn-body, While the latter, by means of the adjnstabilty ,hereinbefore described, will rest against the churn-cover.

In the operation of this device, by the reciprocation of the dasher, the cream is very violently agitated through the perforations in the inner cylinder and dasher, and the fatty matter very quickly released from the sacks or globales.

What I claim as my invention, and desire to secure by Letters Patent,- `1s In churns, Vthe perforated and adjustable cylinder B, provided with ilange a and cap d, the latter being also provided with flange h, as described, and for the purposes set forth. fGEORGE P. UGAN.
